Research suggests that self-esteem can decline in older adulthood. This process could remove a buffer that normally protects individuals against distress-related changes in cortisol secretion. We examined this possibility by testing whether change in self-esteem would predict alterations in cortisol secretion, particularly among older adults who reported high levels of depressive symptoms or perceived stress.

Methods

147 older adults (aged 60+) completed three days of diurnal cortisol measurements at three different time points, namely every two years over a total period of four years. Measures of self-esteem, depressive symptoms, and perceived stress were assessed at T1 and T2. Potential demographic and health-related confounds were measured at baseline (partnership status, SES, mortality risk index, and medication).
